For this requirement the authors have developed an MO head using reflection
polarizing HOE(R-PHOE). This paper describes the design for the R-PHOE,
optical head configuration, fabrication of the R-PHOE and head operation ...

Optical configuration The optical configuration for the MO head using the R-
PHOE is shown in Fig. 2. The Kerr polarization component light generated at a
reflection from the MO disk is reflected at PBS without an appreciable light power
loss ...

In the larger incident angle, the polarizing characteristics close to the condition
desired for R-PHOE in the MO head, which is shown in Fig.1. The incident angle
for the R- PHOE was determined as being 60 degrees, taking into account ...
